Observation of $B \to D^{(*)} K^{-} K_{S}^{0}$ decays using the 2019-2022 Belle II data sample

Belle II Collaboration, F. Abudinén, I. Adachi +575

We present a measurement of the branching fractions of four $B^{0, -} \to D^{(*) +, 0} K^{-} K_{S}^{0}$ decay modes. The measurement is based on data from SuperKEKB electron-positron colli…

Determination of $∣ V_{u b} ∣$ from untagged $B^{0} \to π^{-} ℓ^{+} ν_{ℓ}$ decays using 2019-2021 Belle II data

Belle II Collaboration, K. Adamczyk, L. Aggarwal +588

We present an analysis of the charmless semileptonic decay $B^{0} \to π^{-} ℓ^{+} ν_{ℓ}$ , where $ℓ = e, μ$ , from 198.0 million pairs of $B B ˉ$ mesons recorded by the Belle II…

Measurement of Branching Fraction and Longitudinal Polarization in $B^{0} \to ρ^{+} ρ^{-}$ Decays at Belle II

Belle II Collaboration, F. Abudinén, I. Adachi +584

We present a measurement of the branching fraction and longitudinal polarization of $B^{0} \to ρ^{+} ρ^{-}$ decays. SuperKEKB electron-positron collision data corresponding to 189~fb$^{-…

Observation of Transverse $Λ/ Λ ˉ$ Hyperon Polarization in $e^{+} e^{-}$ Annihilation at Belle

The Belle Collaboration, A. Abdesselam, I. Adachi +445

We report the first observation of the polarization of $Λ/ Λ ˉ$ hyperons transverse to its production plane in $e^{+} e^{-}$ annihilation. We observe a significant polarization that ri…

Search for CP violating charge asymmetry in B^+ -> J/psi K^+ decays

K. Sakai, T. Kawasaki, H. Aihara +136

We present the result of a search for charge asymmetry in B^+ -> J/psi K^+ decays. The CP-violating charge asymmetry is measured to be A_CP(B^+ -> J/psi K^+) = [-0.76 +/- 0.50 (sta…

Measurement of the e+e- -> J/psi ccbar cross section at \sqrt{s} ~10.6 GeV

P. Pakhlov

We present a new measurement of the e+e- -> J/psi ccbar cross section where the ccbar pair can fragment either into charmed hadrons or a charmonium state. In the former case the J/…
